Fold a twin bed sheet horizontally so when you hold one end at the top of your chest, the other end is about ankle length. Adjust for a shorter or longer toga.
Hold the edge of the sheet to the right side of your chest. The short end of the fold you made for length should face inward, toward your body. Wrap the sheet around your body to the left one and a half times. The excess sheet will be at the left side of your chest.
Use safety pins to secure the sheet layers on the right and left side of your chest. This will keep the toga together. Hide the pins in the folds of the sheet.
Throw the excess sheet over your left shoulder. It will drape behind you. Accessorize your toga with a metallic belt around the waist, if desired. This will help keep it from slipping off.
